It's worth mentioning that while the Xperia XZ Premium units in Japan won't taste Oreo until December, there is a high change the update will arrive to other parts of the world earlier.

That said, we can safely assume that Xperia XZ Premium will be Sony's first smartphone to get Android Oreo. We can also expect some other Xperia devices to get the update around the same time.

To remind you, last year, Sony released Nougat starting with the Xperia X Performance in November. However, before the roll out the update was tested under the Xperia Beta Program. Android Oreo is also likely to go through a similar process this year before the official roll out.
